Ed Clancy, Geraint Thomas, Peter Kennaugh and Steven Burke posted a time of three minutes 51.659 seconds, beating Australia's Jack Bobridge, Glenn O'Shea, Rohan Dennis and Michael Hepburn, who clocked three minutes 54.581 seconds.
The British four, who are current world champions, were roared on by a partisan crowd, including Tony and Cherie Blair.
